Does pharmaceutical advertising affect journal publication about dietary supplements?

<p>Abstract</p> <p>Background</p> <p>Advertising affects consumer and prescriber behaviors. The relationship between pharmaceutical advertising and journals' publication of articles regarding dietary supplements (DS) is unknown.</p> <p>Methods</p> <p>We reviewed one year of the issues of 11 major medical journals for advertising and content about DS. Advertising was categorized as pharmaceutical versus other. Articles about DS were included if they discussed vitamins, minerals, herbs or similar products. Articles were classified as major (e.g., clinical trials, cohort studies, editorials and reviews) or other (e.g., case reports, letters, news, and others). Articles' conclusions regarding safety and effectiveness were coded as negative (unsafe or ineffective) or other (safe, effective, unstated, unclear or mixed).</p> <p>Results</p> <p>Journals' total pages per issue ranged from 56 to 217 while advertising pages ranged from 4 to 88; pharmaceutical advertisements (pharmads) accounted for 1.5% to 76% of ad pages. Journals with the most pharmads published significantly fewer major articles about DS per issue than journals with the fewest pharmads (P < 0.01). Journals with the most pharmads published no clinical trials or cohort studies about DS. The percentage of major articles concluding that DS were unsafe was 4% in journals with fewest and 67% among those with the most pharmads (P = 0.02). The percentage of articles concluding that DS were ineffective was 50% higher among journals with more than among those with fewer pharmads (P = 0.4).</p> <p>Conclusion</p> <p>These data are consistent with the hypothesis that increased pharmaceutical advertising is associated with publishing fewer articles about DS and publishing more articles with conclusions that DS are unsafe. Additional research is needed to test alternative hypotheses for these findings in a larger sample of more diverse journals.</p

A Pilot Randomized Controlled Trial of a Mindfulness Program for Filipino Children

Objectives This study examines the feasibility and acceptability of a local adaptation of a mindfulness-based cognitive therapy (MBCT) program for Filipino school children, called Kamalayan, that was facilitated by trained public school teachers. It also presents preliminary evidence of program effects on the children’s depressive and anxiety symptoms and difficulties in emotion regulation. Methods We utilized a randomized controlled design with an active control condition. Filipino elementary and high school students aged 9 to 16 years old from low-resource schools were randomly assigned to the Kamalayan (n = 87) or the active control Handicrafts condition (n = 99). Changes in outcomes from baseline, immediate post-intervention, and 2-month follow-up were assessed using multilevel modeling. Results Participation in the Kamalayan program did not affect depression, anxiety, or emotion regulation. Impulse control difficulties increased for the Handicrafts group across post-intervention and follow-up but remained stable for Kamalayan participants. Depressive symptoms decreased over time for the Handicrafts group but remained stable for the Kamalayan condition. Implementation issues qualify the absence of program effects, such as the impracticability of delivering after-school sessions in the public school context, program content that may be discordant with cognitive-developmental and cultural considerations, and the inadequacy of the personal mindfulness practice of the paraprofessional facilitators. Conclusions The findings reaffirm the importance of using active control groups and considering the capacities of facilitators in evaluating the effects of mindfulness-based interventions. Testing mindfulness-based interventions in low-resource, non-Western school settings require deeper contextual adaptation and facilitator preparation

Yoga Enhances Positive Psychological States in Young Adult Musicians

Although yoga has been shown to be a viable technique for improving the performance of the mind and body, little attention has been directed to studying the relationship between yoga and the psychological states of flow and mindfulness. Musicians enrolled in a 2-month fellowship program in 2005, 2006 and 2007 were invited to participate in a yoga and meditation program. Fellows not participating in the yoga program were recruited separately as controls. All participants completed baseline and end-program questionnaires evaluating dispositional flow, mindfulness, confusion, and music performance anxiety. Compared to controls, yoga participants reported significant decreases in confusion and increases in dispositional flow. Yoga participants in the 2006 sample also reported significant increases in the mindfulness subscale of awareness. Correlational analyses revealed that increases in participants' dispositional flow and mindfulness scores were associated with decreases in confusion and music performance anxiety. This study demonstrates the commonalities between positive psychology and yoga, both of which are focused on enhancing human performance and promoting beneficial psychological states. The results suggest that yoga and meditation may enhance the states of flow and mindful awareness, and reduce confusion
